Clinical Practice Guidelines for Chronic Medical Conditions and Preventive Services

Community Health Network of Washington and Community Health Plan of Washington use guidelines for chronic diseases (including medical and behavioral health conditions) and for preventive services, as listed below. Reference is made to the pertinent evidence-based, peer-reviewed guidelines from Nationally recognized agencies. The guidelines are intended to help guide providers in their care of our members including CHNW Cascade Select, CHPW Medicare, CHPW Apple Health-Integrated Managed Care, and CHPW Behavioral Health Services Only members. The guidelines also ensure that the criteria used for utilization management decisions are current.

All guidelines are reviewed at a minimum of once every two years. The Clinical Quality Improvement Committee (CQIC), which includes medical and behavioral health providers and quality specialists, participates in this review and approves any changes. Paper copies of the guidelines are available for members or providers on request, as well as at the links provided.

Utilization Management

Utilization management is a process of reviewing whether care is medically necessary and appropriate for patients. Our process includes the use of prior authorization, concurrent review, and post-service review to ensure appropriateness, medical need, and efficiency of health care services, procedures, and the appropriate place of service.

Who does the review?

The review is done by the appropriate licensed staff, which includes — but is not limited to — nurses, medical director, and pharmacist. Community Health Plan of Washington staff is available to discuss any utilization management process, authorization, or denial.

Prior Authorization review is the process of reviewing certain medical, surgical, and behavioral health services. This is to ensure the medical necessity and appropriateness of care are met prior to services being delivered.

Approvals for Services

Community Health Plan of Washington staff and providers determine whether services are approved or denied. We use information from your doctor to do this. We also look at medical standards. Our decisions are fair and equal. We follow these rules:

  • Utilization Management decision makers approve or deny based only on whether the care and service are appropriate and whether the care or service is covered.
  • Community Health Plan of Washington does not reward providers or others for denying coverage or care.
  • Community Health Plan of Washington does not offer financial incentives to encourage Utilization Management decision makers to make decisions that result in under-using care or services.

How We Evaluate New Technologies

Community Health Plan of Washington is committed to keeping up with new technologies. This means we review new tests, drugs, treatments, and devices and new ways to use current tests, drugs, treatments, and devices.

New technologies are evaluated on an ongoing basis. They are approved based on standards that protect patient safety.

We handle new technology requests for a specific member in a timely manner. They are processed as prior authorization requests. All requests are subject to current benefits and coverage limitations. Members denied a service or referral have the right to submit an appeal.

To learn more about the decision process or whether a specific new technology is covered by Community Health Plan of Washington, please call our Customer Service team at 1-800-942-0247 (TTY Relay: Dial 711), Monday through Friday, 8:00 a.m. to 8:00 p.m.

Appeal and Payment Dispute Rights

Appeal Rights

Contracted Provider: In accordance with the Medicare Managed Care guidance, contracted providers do not have an appeal right. Community Health Plan of Washington (CHPW) has a review process to address contracted provider claim issues. Requests for contracted provider claim reviews should be received by CHPW within 120 days from the date of the Provider Remittance Advice (PRA). A copy of the PRA and supporting documentation (i.e., medical records) must be submitted with the request.

Non-Contracted Provider: In accordance with the Medicare Managed Care guidance, non-contracted providers have appeal rights. Appeal rights apply to any claim CHPW has denied payment. Requests for payment appeals must include a completed and signed “Waiver of Liability” (WOL) statement. CHPW cannot begin the appeals process without a signed WOL. Requests for appeals that do not include a WOL will be dismissed. Requests for payment appeals must be filed within 60 calendar days of receiving the PRA. A copy of this PRA and supporting documentation must be submitted with the appeal request. CHPW must make a decision regarding the appeal within 60 calendar days from the date the appeal request is received.

If CHPW upholds the initial payment denial following review of the appeal or does not make a decision within 60 calendar days from the date the appeal request was received, CHPW will submit the appeal request to the IRE for review. The IRE will review the appeal and notify the provider in writing of the decision. If CHPW upholds the original claim denial, non-contracted providers have the right to ask the CMS contracted IRE to review the appeal.

Payment Dispute Rights

Contracted Providers: Refer to Contracted Provider Appeal

Non-Contracted Providers: In accordance with Medicare Managed Care guidance, non-contracted providers have payment dispute rights. Payment dispute rights apply to any claim the provider contends the amount paid for a covered service is less than the amount that would have been paid by Original Medicare. Payment dispute rights apply to any claim there is a disagreement between the non-contracted provider and CHPW regarding the decision to pay for a different service than the billed service. Requests for payment disputes must be filed within 120 calendar days of the PRA. CHPW must make a decision regarding the payment dispute within 30 calendar days from the date the payment dispute is received.

Payment disputes are subject to CMS review as CHPW is required to pay non-contracted providers the same amount the provider would have received had the provider billed Original Medicare. The non-contracted provider payment dispute process can not be used to challenge payment denials that result in zero payment. Payment denials may be appealed as described in the Non-Contracted Provider Appeal section above.

Question about the non-contracted provider appeal or payment dispute process can be directed to our Customer Service department toll-free at 1-800-942-0247 (TTY 711), 7 days a week, from 8:00 a.m. to 8:00 p.m.
